class viam.app.viam_client.ViamClient[source]

gRPC client for all communication and interaction with app.

ViamClient class for creating and managing specialized client instances. There is currently 1 way to instantiate a ViamClient object:

ViamClient.create_from_dial_options(...)

classmethod create_from_dial_options(dial_options: viam.rpc.dial.DialOptions, app_url: str | None = None) → typing_extensions.Self[source]

Async:

Create ViamClient that establishes a connection to the Viam app.

dial_options = DialOptions.with_api_key("<API-KEY>", "<API-KEY-ID>")
ViamClient.create_from_dial_options(dial_options)

Parameters:

dial_options (viam.rpc.dial.DialOptions) – Required information for authorization and connection to app. creds and auth_entity fields are required.
app_url – (Optional[str]): URL of app. Uses app.viam.com if not specified.

Raises:

ValueError – If the input parameters are missing a required field or simply invalid.

Returns:

The ViamClient.

Return type:

Self

property data_client: viam.app.data_client.DataClient

Instantiate and return a DataClient object used to make data and data_sync method calls. To use the DataClient, you must first instantiate a ViamClient.

async def connect() -> ViamClient:
    # Replace "<API-KEY>" (including brackets) with your API key and "<API-KEY-ID>" with your API key ID
    dial_options = DialOptions.with_api_key("<API-KEY>", "<API-KEY-ID>")
    return await ViamClient.create_from_dial_options(dial_options)

async def main():
    viam_client = await connect()

    # Instantiate a DataClient to run data client API methods on
    data_client = viam_client.data_client

property app_client: viam.app.app_client.AppClient

Instantiate and return an AppClient used to make app method calls. To use the AppClient, you must first instantiate a ViamClient.

async def connect() -> ViamClient:
    # Replace "<API-KEY>" (including brackets) with your API key and "<API-KEY-ID>" with your API key ID
    dial_options = DialOptions.with_api_key("<API-KEY>", "<API-KEY-ID>")
    return await ViamClient.create_from_dial_options(dial_options)


async def main():
    viam_client = await connect()

    # Instantiate an AppClient called "fleet" to run fleet management API methods on
    fleet = viam_client.app_client

property ml_training_client: viam.app.ml_training_client.MLTrainingClient

Instantiate and return a MLTrainingClient used to make ml_training method calls. To use the MLTrainingClient, you must first instantiate a ViamClient.

async def connect() -> ViamClient:
    # Replace "<API-KEY>" (including brackets) with your API key and "<API-KEY-ID>" with your API key ID
    dial_options = DialOptions.with_api_key("<API-KEY>", "<API-KEY-ID>")
    return await ViamClient.create_from_dial_options(dial_options)


async def main():
    viam_client = await connect()

    # Instantiate an MLTrainingClient to run ML training client API methods on
    ml_training_client = viam_client.ml_training_client

property billing_client: viam.app.billing_client.BillingClient

Instantiate and return a BillingClient used to make billing method calls.: To use the BillingClient, you must first instantiate a ViamClient.

async def connect() -> ViamClient:
    # Replace "<API-KEY>" (including brackets) with your API key and "<API-KEY-ID>" with your API key ID
    dial_options = DialOptions.with_api_key("<API-KEY>", "<API-KEY-ID>")
    return await ViamClient.create_from_dial_options(dial_options)


async def main():
    viam_client = await connect()

    # Instantiate a BillingClient to run billing client API methods on
    billing_client = viam_client.billing_client

property provisioning_client: viam.app.provisioning_client.ProvisioningClient

Instantiate and return a ProvisioningClient used to make provisioning method calls. To use the ProvisioningClient, you must first instantiate a ViamClient.

async def connect() -> ViamClient:
    # Replace "<API-KEY>" (including brackets) with your API key and "<API-KEY-ID>" with your API key ID
    dial_options = DialOptions.with_api_key("<API-KEY>", "<API-KEY-ID>")
    return await ViamClient.create_from_dial_options(dial_options)


async def main():
    viam_client = await connect()

    # Instantiate a ProvisioningClient to run provisioning API methods on
    provisioning_client = viam_client.provisioning_client

close()[source]: Close opened channels used for the various service stubs initialized.

async connect_to_machine(*, address: str | None = None, id: str | None = None) → viam.robot.client.RobotClient[source]

Connect to a machine using existing credentials.

A connection can be attempted using either the machine’s address or its ID. If both an address and ID are provided, the address will take precedence and the ID will be ignored.

async def connect() -> ViamClient:
    # Replace "<API-KEY>" (including brackets) with your API key and "<API-KEY-ID>" with your API key ID
    dial_options = DialOptions.with_api_key("<API-KEY>", "<API-KEY-ID>")
    return await ViamClient.create_from_dial_options(dial_options)


async def main():
    viam_client = await connect()

    # Connect to a machine and obtain a RobotClient
    # Replace "<MACHINE_ADDRESS>" (including brackets) with your machine's connection address
    machine = await viam_client.connect_to_machine(address="<MACHINE_ADDRESS>")

Parameters:

address (Optional[str]) – The address (FQDN) of the machine. Defaults to None.
id (Optional[str]) – The ID (as a UUID) of the machine. Defaults to None.

Raises:

ValueError – If neither an address nor ID is provided.

Returns:

The active connection to the machine.

Return type:

RobotClient
